[0035] The steel pipe will initially be transported or placed on the first ramp 12 under the transportation of other conveying mechanisms. The ramp structures in the present application are all plates with a right-angled triangle cross-section. When the steel pipe is placed on the slope of the first ramp 12, the steel pipe begins to roll down along the slope. The two first support plates 14 have the same plate thickness and are both lower than the height of the first ramp 12 and the first baffle 13. The left ends of the two first support plates 14 are respectively located on the front and rear sides of the first ramp 12. The steel pipe is transferred from the first ramp 12 to the first support plate 14 at the junction of the slope of the first ramp 12 and the top end of the first support plate 14. At this time, the steel pipe turns to horizontal rolling to the right; the scraper of the cleaning assembly can block the steel pipe on the first support plate 14 and clean the surface of the end of the steel pipe.
[0036] refer to Figure 1 and Figure 2 The limiting assembly includes a beam 21 fixed on the lifting mechanism, the beam 21 is parallel to the horizontal plane, and the moving direction of the beam 21 is perpendicular to the horizontal plane. A first cylinder 22 is fixedly installed on the left side of the beam 21, and the first cylinder 22 is located below the top end surface of the beam 21. The axial direction of the output end of the first cylinder 22 is at an angle of 120° with the horizontal plane. A first limiting plate 23 is installed on the output end of the first cylinder 22, and the length direction of the first limiting plate 23 is parallel to the axial direction of the output end of the first cylinder 22. A second limiting plate is installed on the right side of the beam 21, and the left side wall of the second limiting plate is V-shaped. The angle between the plane of the upper half of the left side wall of the second limiting plate and the horizontal plane is 120°, and the angle between the plane of the lower half of the left side wall of the second limiting plate and the horizontal plane is 60°.
[0037] It should be noted that: this lifting mechanism can be arranged on the right side wall surface of the cache table 11, specifically, a first track 15 is arranged on the right side wall of the cache table 11, and a first slider 16 is arranged on the first track 15. The first slider 16 can move up and down along the first track 15. The lifting and lowering of the limit assembly is completed by the lifting and lowering of the lifting mechanism here, that is, the height of the limit assembly is adjusted by adjusting the height of the first slider 16. The left end of the crossbeam 21 in the limit assembly is fixed on the right side wall of the first slider 16. In this scheme, the steel pipe bundle can be regarded as a structure similar to a hexagonal prism, and the stacking units are arranged in sequence along the front and rear directions. In order to form a frame structure, the limit assembly can match Accommodate steel pipe bundles, the axial direction of the steel pipes in the steel pipe bundle is parallel to the front-to-back direction, the planes where the angles of 60° and 120° are located are perpendicular to the front-to-back direction, this crossbeam 21 includes two parallel plates, the left end of the plate is fixed to the right side wall of the first slider 16, a cylinder mounting frame is fixedly connected to the bottom end of the crossbeam 21, the first cylinder 22 is fixedly mounted on this cylinder mounting frame, a first limiting plate 23 is fixedly connected to the output end of the first cylinder 22, the plate surface of the first limiting plate 23 is parallel to the length direction of the output end of the first cylinder 22, the first limiting plate 23 can be moved obliquely upward under the drive of the first cylinder 22, and the top of the first limiting plate 23 passes through the crossbeam 2 1After the first limit plate 23 is moved upward in a direction of 120° to the horizontal plane, the right side wall of the portion higher than the cross beam 21 on the first limit plate 23 can provide support for the formation of the steel pipe bundle. The cross beam 21 is provided with a horizontal screw structure, and the position of the screw nut on the screw structure can be adjusted by a knob or a hand wheel at the right end of the cross beam 21. The second limit plate is fixed on the screw nut. The first limit plate 23 and the second limit plate here can adjust the distance between the two limit plates by adjusting the position of the screw nut on the screw structure, so as to cope with different stacking operations, that is, to cope with the stacking of steel pipes of different diameters or the stacking of steel pipe bundles of different sizes, the limit plate needs to be adjusted. The spacing between the two limit plates at the assembly, the lower half of the second limit plate is fixed on the screw nut, the left side wall of the lower half of the second limit plate can be regarded as the second track 24, the second track 24 is tilted, the length direction of the second track 24 and the horizontal plane The angle is 60°, and a second slider 25 is slidably arranged on the second track 24. A plate body is hinged on the second slider 25, and the hinge axis of this plate body is parallel to the front and rear directions. This plate body can be regarded as the upper half of the second limit plate, and a cylinder is also hinged on the side walls of the front and rear sides of the second slider 25. The output end of this cylinder is hinged to the side wall of the upper half of the second limit plate. The extension and retraction of this cylinder can adjust the angle between the upper half of the second limit plate and the horizontal plane.
[0038] refer to Figure 1 and Figure 3The feeding assembly includes a second cylinder 31, a third cylinder 32, a second ramp 35 and a third track 33. The moving directions of the output ends of the second cylinder 31 and the third cylinder 32 are perpendicular to the horizontal plane. A third slider 34 driven by a motor is provided on the third track 33. The third slider 34 can move in the left and right directions on the top end surface of the third track 33. The third cylinder 32 is fixed on the third slider 34. The bottom area on the left side of the second ramp 35 is hinged to the top end of the output end of the third cylinder 32. The second cylinder 31 is located on the right side direction of the third track 33, and the output end of the second cylinder 31 is always in contact with the bottom end surface of the second ramp 35.
[0039] It should be noted that when the steel pipe is transferred from the buffer table 11 to the limit assembly, the movement mode of the feeding assembly is as follows: first, the output ends of the second cylinder 31 and the third cylinder 32 begin to be accurately lifted under the control of the control system, and at this time, the second ramp 35 supported by the second cylinder 31 and the third cylinder 32 is first adjusted to have a slope parallel to the horizontal plane, and then the second ramp 35 begins to rise under the extension of the output ends of the second cylinder 31 and the third cylinder 32, and during the rising process, the slope of the second ramp 35 is always parallel to the horizontal plane, and the second ramp 35 is limited by the first baffle 13. A plurality of steel pipes stay in the top right area of the buffer platform 11. As the second ramp 35 rises, the height of the second ramp 35 exceeds the height of the first support plate 14. At this time, the steel pipes are driven by the second ramp 35 to move upward and leave the buffer platform 11. When the bottom end height of the second ramp 35 exceeds the top height of the steel pipe bundle being formed in the limiting assembly and the top surface height of the first baffle 13, the third slider 34 on the third track 33 starts to move in the direction of the second cylinder 31. The steel pipes on the second ramp 35 move in the process of the third slider 34 moving. In the process of the second ramp 35 moving to the right, the steel pipes on the second ramp 35 do not separate from the second ramp 35. Here, a rubber pad can be added to the top plate surface of the second ramp 35 to increase friction and reduce the rolling amplitude of the steel pipe when the second ramp 35 moves to the right. Alternatively, the height of the second cylinder 31 is slightly lowered, so that the top surface of the second ramp 35 is in an inclined state, and the inclination angle of the top surface does not exceed 20°. As a result, during the movement of the second ramp 35, the steel pipes on the second ramp 35 stay on the second ramp 35 due to factors such as friction, and the movement of the third slider 34 causes the right end of the second ramp 35 to extend to each limit assembly. When the right end of the second ramp 35 approaches the left side wall of the second limit plate in the horizontal direction (the distance is less than 2 cm) or the right end of the second ramp 35 moves to the right end area of the highest layer of the current steel pipe bundle, the second cylinder 31 descends or the third cylinder 32 rises, and at the same time, the third slider 34 moves to the left, so that the steel pipes on the second ramp 35 roll along the slope to leave the second ramp 35, and stay one by one in the top area of the steel pipe bundle, completing the laying of a layer of steel pipes on the steel pipe bundle.
[0040] refer to Figures 4 to 6 The scraper platform includes a support platform and a scraper. A fourth track 48 is provided on the top surface of the support platform. A fourth slider 49 is provided on the fourth track 48. The scraper is installed at the top of the fourth slider 49. The scraper includes a lifting platform 410 and a shell 45 arranged from bottom to top. The bottom end of the lifting platform 410 is fixedly connected to the fourth slider 49. The top of the lifting platform 410 is hinged to the two side walls of the bottom end of the shell 45. The shell 45 is a rectangular structure. A notch 46 is opened in the middle area of the left side of the shell 45. A scraper mechanism is provided in the shell 45. The notch 46 is used to accommodate the steel pipe. The scraper mechanism is used to remove oil from the surface of the steel pipe at the notch 46.
[0041] It should be noted that the lifting platform 410 includes four columns and a platform on the top surface, the bottom end of each column is fixed on the top surface of the fourth slider 49, and the bottom of the scraper is hinged to the top platform of the lifting platform 410; in the initial state of this scraper, the scraper can be rotated and the height of the scraper can be adjusted with the help of the hinge shaft at the bottom of the scraper and the lifting platform 410, so that the shell 45 is rotated to the left direction of the notch 46, and the height of the bottom edge of the notch 46 of the shell 45 can be slightly lower than the height of the first support plate 14. After the steel pipe rolls down from the first ramp 12, the steel pipe rolls to the notch 46 of the shell 45, and the steel pipe is blocked by the shell 45 and stops. If the steel pipe is blocked and rebounds to leave the shell 45, the second ramp 35 can be lifted, and the steel pipe can be pushed to the notch 46 of the shell 45 with the help of the slope surface of the second ramp 35. The notch 46 here is set to make the shell 45 form a U-shaped structure.
[0042] refer to Figure 5 and Figure 6 The scraping mechanism includes a cloth strip 41, a retractable assembly 42, a clamping mechanism 43 and a tensioning mechanism 44. The two ends of the cloth strip 41 are fixed by the retractable assembly 42, the middle part of the cloth strip 41 is hooked by the output end of the tensioning mechanism 44, the middle part of the cloth strip 41 is located at the notch 46 and the middle area of the cloth strip 41 is stretched into a V-shaped structure, the opening of the V-shaped structure faces the left side, and there are two clamping mechanisms 43, which are used to clamp the left and right sides of the V-shaped structure and make the upper and lower parts of the V-shaped structure fit together.
[0043] It should be noted that the retractable assembly 42 mentioned in the present solution includes two rollers arranged in the inner cavity of the shell 45, the rollers are driven by a motor or a cylinder, the axis directions of the two rollers are parallel to the front-back direction, and two bins are arranged on the right side of the inner cavity of the shell 45. The bins are formed by metal plates, and the bins are rectangular chambers in the inner cavity of the shell 45. The rollers of the two retractable assemblies 42 are respectively installed in the central area of the two bins. The two bins here can be used to isolate the used and unused cloth strips 41 to prevent the scraped liquid from contaminating the unused cloth strips 41 when the scraper moves. The upper bin is used to roll up the unused cloth strips 41, and the entrance and exit of the upper bin is located at the top of the left wall of the upper bin. The lower bin is used to roll up the used cloth strips 41, and the entrance and exit of the lower bin is located at the bottom of the left wall of the lower bin. The clamping mechanism 43 includes a cylinder embedded in the shell 45, and the output end of the cylinder is fixedly connected with a rod body. The rod bodies pushed by the upper and lower cylinders are close to each other, so that the upper and lower cloth strips 41 are attached to each other, and the steel pipe at the notch 46 is surrounded by the cloth strip 41 through the clamping of the two groups of clamping mechanisms 43, and then the steel pipe is fixed by the retractable assembly 42. The tightening mechanism 44 pulls the cloth strip 41 to the right, so that the cloth strip 41 can be relatively tightly attached to the surface of the steel pipe. Support rods 47 are arranged above and below the notch 46 to provide support for the cloth strip 41. The tensioning mechanism 44 includes a cylinder installed between the two silos, and the output end of the cylinder is fixedly connected to a cylinder. The axis of the cylinder is parallel to the front and rear directions. The side wall of the left area of the cylinder is provided with upper and lower grooves, and the inner cavities of the two grooves are connected. Through the support rods 47 arranged in the upper and lower directions of the notch 46 and the connected grooves arranged at the tensioning mechanism 44, the shell is satisfied. In the inner cavity 45, the middle section of the cloth strip 41 is stretched into a V-shaped structure at the notch 46, and the clamping mechanism 43 is used to clamp the cloth strip 41 up and down to surround the steel pipe that stops at the notch 46. The cloth strip 41 is pulled to the right by the tensioning mechanism 44, and at the same time, the roller of the retractable assembly 42 keeps the roller from rotating, so that the cloth strip 41 is stretched and fits the surface of the steel pipe more closely. In addition, a through hole can be opened at the bottom edge of the inner cavity of the shell 45, and a negative pressure air pump can be plugged into the through hole to discharge the scraped liquid from the shell 45 in time, so as to avoid excessive liquid in the shell 45, which may cause the scraper to fail or even contaminate the steel pipe.
[0044] refer to Figure 1 and Figure 4 A fifth slider 411 is also provided on the fourth track 48, and a second baffle 412 is fixedly installed on the fifth slider 411. A lifting mechanism 413 is also provided in the stacking assembly. The lifting mechanism 413 is located between the buffer tables 11, and the top surface of the lifting mechanism 413 is V-shaped, and a plurality of spherical protrusions are provided on the top surface of the lifting mechanism 413.
[0045] It should be noted that the sliding of the second baffle 412 on the fourth track 48 can be used to adjust the position of the steel pipe, so that when the stacking of the steel pipe bundle is completed, the ends are in basically the same position because they have been in contact with the second baffle 412, so that the alignment of the steel pipes in the formed steel pipe bundle is relatively high; the lifting mechanism 413 is used to rise through the top end of the lifting mechanism 413 when the second baffle 412 pushes the steel pipe, and the top V-shaped surface of the lifting mechanism 413 is used to prevent the steel pipe from rolling, and combined with a number of spherical protrusions on the end face, the friction force on the horizontal movement of the steel pipe can be reduced, making it relatively easy to be pushed by the second baffle 412. The spherical protrusions here are arranged in an equidistant array on the top surface of the lifting mechanism 413. The main body of the lifting mechanism 413 is a cylinder structure, and the moving direction of the output end of the cylinder structure is perpendicular to the horizontal plane.
[0046] refer to Figure 1 The unloading conveying assembly includes a plurality of roller frames arranged in a row. The roller frames are divided into two types, one is a horizontal roller frame for supporting the bottom end of the steel pipe bundle, and the other is a forked roller frame for supporting both sides of the bottom of the steel pipe bundle.
[0047] When the steel pipe bundle is gradually formed, the height of the limit assembly gradually decreases until the crossbeam 21 is slightly lower than the horizontal roller on the horizontal roller frame. The horizontal roller is driven by a motor. The above two roller frames are arranged alternately in the front and rear directions. The forked roller frame is provided with two inclined rollers, which can support the left and right sides of the bottom of the steel pipe bundle. The forked roller frame is also provided with a screw structure-screw nut-handwheel. By shaking the handwheel, the position of the screw nut on the screw structure can be adjusted. One of the inclined rollers on the forked roller frame is installed on the screw nut, that is, the spacing between the two rollers on the forked roller frame here can also be adjusted according to the specifications of the steel pipe bundle.
[0048] refer to Figure 7The limiting assembly only needs to support four of the six side walls of the steel pipe bundle through the crossbeam 21, the first limiting plate 23 and the second limiting plate to complete the limiting of the steel pipe bundle. The specific arrangement is that the steel pipes in contact with each other in the steel pipe bundle are arranged in a staggered manner. The middle layer of the steel pipe bundle has the largest number of single-layer steel pipes. This layer is supported by the first limiting plate 23 and the second limiting plate in the left and right directions for position limitation. Each layer of steel pipes above this layer is stacked layer by layer, and only when stacking The upper half of the second limit plate is used for blocking. Since the limit assembly will gradually descend after each layer of steel pipes is placed, when the steel pipes roll from the second slope plate 35 and fall onto the steel pipe bundle, the distance between the currently fallen steel pipe and the steel pipe bundle below is very small. Therefore, when each layer of steel pipes is placed, the impact force on the steel pipe bundle in the lower area is relatively small. Therefore, no additional support is provided for the upper half of the steel pipe bundle. Only through the staggered arrangement of each layer of steel pipes, the first limit plate and the second limit plate indirectly support each layer of steel pipes in the upper half of the steel pipe bundle.
[0049] refer to Figure 8 When the steel pipe bundle is stacked, the limiting assembly descends to the bottom end of the steel pipe bundle and can contact the rollers of the unloading conveying assembly. The rollers are respectively the horizontal rollers on the horizontal roller frame and the left and right inclined rollers on the forked roller frame. The three sides of the lower half of the steel pipe bundle are supported by the above rollers. Similar to the limiting assembly, the left and right inclined rollers also indirectly support the upper half of the steel pipe bundle, that is, the steel pipes in the middle layer of the steel pipe bundle are in contact with the left and right rollers. The horizontal roller can be driven by a motor, and the left and right inclined rollers can be driven rollers to complete the conveying of the steel pipe bundle along the arrangement direction of the roller frame of the unloading conveying assembly.
[0050] The implementation principle of the embodiment of the present application is as follows: first, the steel pipes are placed in the buffer table 11 one by one. When the steel pipes move from left to right under the support of the buffer table 11, the ends of the steel pipes are blocked by the scraper. The scraper uses the internal scraping mechanism to make the cloth strip 41 tight on the surface of the end of the steel pipe, and scrapes off the liquid accumulated on the surface of the end of the steel pipe under the movement of the scraper, and adjusts the position of the steel pipe through the second baffle plate 412, so that the alignment of the steel pipe entering the limiting component can be relatively high. After the steel pipe is cleaned, the shell 45 rotates along its own hinge axis and adjusts the height of the lifting platform 410, so that the shell 45 can be detached from the steel pipe without affecting the position of the steel pipe. The steel pipe can be concentrated in the top right area of the buffer table 11 by lifting the second ramp plate 35; the feeding assembly is first adjusted to the level of the top surface through the second ramp plate 35, and then lifted to the height of the steel pipe exceeding the first baffle plate 13, and then the second ramp plate 35 Driven by the third slider 34, it moves to the right to transfer the steel pipe from the buffer table 11 to the limiting assembly. After completing the stacking of a single-layer steel pipe in the steel pipe bundle, the limiting assembly can lower its own height, and the height value is close to the height of the single-layer steel pipe, so that the height required to be lifted by the feeding assembly each time the steel pipe is transferred can be basically the same. When the limiting assembly completes the stacking, the limiting assembly descends to the steel pipe bundle and can be supported by the unloading conveying assembly. At this time, the horizontal rollers on the horizontal roller frame are driven to complete the transfer of the steel pipe bundle. The two inclined rollers on the forked roller frame are driven rollers, which are mainly used to support the bottom two sides of the steel pipe bundle. The steel pipe packaging device mentioned in this scheme can realize the stacking of steel pipes by layer, and the steel pipes are cleaned during stacking, which can reduce the errors and omissions caused by manual visual inspection and the time-consuming cleaning, improve the alignment of the steel pipe ends in the steel pipe bundle, and improve the overall packaging quality of the steel pipes.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
